CLAMPING DEVICE FOR BROOM-HEADS.

SPECIFICATION forming part of Letters Patent No. 639,978, dated December 26, 1899.

Application filed April 25, 1899. Serial No. 714,435. (No model.)

To all whom, it may concern.-

Be it known that we, SAMUEL PARKER HERRON and CHARLES FREDRICK GRAY, of Bertha, in the county of Knox and State of Kentucky, have invented a new and Improved Olamping Device for Broom-Heads, of which the following is a full, clear, and exact description.

The object of our invention is to provide a simple device adapted for securely binding together the straw or other material employed in the construction of the brush-sections of brooms, the device being located at the head of such sections.

A further object of the invention is to so construct the clamping device for brooms that it will enable even an unskilled person to group and correctly set up the straw and firmly secure it in desired position.

Another object of the invention is to provide the clamping device with means for receiving and holding the handle-section of a broom.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forminga part of .this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of the brushsection of a broom and a portion of the handle and a perspective view of the improved clamping device applied to the brush-section and handle of the broom. Fig. 2.is a perspective View of the body of the said clamp. Fig. 3 is an inner face view of one member of the binding-section of the device; and Fig. 4 is a vertical section through the complete binding-section of the clamp, illustrating the manner in which the members of the said binding-section are connected.

The clamp consists, primarily, of a'body A and a binding-section B. The body A comprises asleeve 10, preferably having a downward inclination and provided at opposite sides with openings 11. In connection with the said sleeve opposing jaws 12 and 13 are employed, which jaws are curved outwardly and downwardly in opposite directions. The

jaws are of rectangular skeleton form, and the material employed is preferably springwire. The corresponding side members of the jaws are twisted together, forming at each side of the upper portion of the body a shank l4, and the shanks of the jaws are passed upward into the sleeve 10 and out through the openings 11 and are held attached to the sleeve in any suitable or approved manner.

Usually the attachment is effected by carryits inner face and also a transverse groove 17, the groove 17 being located at the bottom of the plate, while the eyes 16 are located one at the top and one at each side of the center of the plate. The eyes 16 are adapted to receive curved arms 20, preferably made of spring- Wire, the curvature of the arms being most decided at their'extremities, and these arms extend about equal distances beyond each side of the plate, as shown in both Figs. 1 and 3. Each plate 15 is provided at its center with an inwardly-extending horizontal tubular stud 18, and the bores of the studs are in two diameters, consisting of an outer enlarged portion or chamber a and an inner reduced portion a. The bores of the tubular studs extend through the plates 15, and said studs are preferably tapering, and when the members of the binding-sections are properly assembled the inner ends of the studs 18 will be quite close together, as shown in Fig. 4, and the two members of the binding-section B are connected by abolt 19, passed through both of the studs 18, the head of said bolt, which is shaped to receive a screwdriver, being within the enlarged portion of the bore of one stud and the nut in the enlarged portion of the bore of the opposing stud, as is also shown in Fig. 4; but the nut may be omitted and the bolt be screwed into the 0pposing stud 18.

In operation the handle is placed in the sleeve 10, the straw comprising the brushsection of the broom is properly assembled, and the head or upper portion of the assembled straw is introduced between the jaws 12 and 13 of the body of the clamp. A member of the binding-section is then made to engage with each jaw, the engagement being such that the curved ends of the arms 20 of the bindingsection partially embrace the side portions of the jaws of the body and the bottom portion of the jaws 12 and 13 of the body enter the grooves 17 in the plates 15 of the members of the said binding-section. The bolt 19 is then passed through one stud 18 into the other, and the nut is screwed up on the bolt until the jaws and binding-section securely clamp the upper portion of the brush-section of the broom, effectually preventing the escape of any straw and rendering the broom-section much stronger than heretofore.

It is obvious that a novice may readily form a broom by the use of a clamp such as has been above described, and that the ends of the connecting-bolt 19 being within the plane of the outer faces of the plates 15 of the hinding-section the outer faces of the clamp are practically smooth and present no surfaces liable to mar polished woodwork or catch any fabric.

- Having thus described our invention, we claim as new and desireto secure by Letters Patent- 1. A broom-clamp, comprising a body consisting of opposing jaws adapted to receive between them the straw of a broom, a binding-section comprising oppositely-extended curved arms arranged for engagement with each of said jaws, and a locking device for the binding-section, whereby the binding-section and the jaws may be made to tightly embrace the straw of the brush-section of the broom, as described.

2. A broom-clamp, consisting. of opposing spring-jaws, a sleeve connected with the said j aws,a binding-section comprising oppositelyextended curved arms arranged for engagement with the jaws, and a locking device for the binding-section, as and for the purpose specified.

3. A broom-clamp, comprising a body-section consisting of opposing oppositely-curved spring-jaws, and means for connecting the jaws with a handle,and a binding-section comprising two members, each member consisting of a center plate, arms carried by the center plate and adapted for engagement with the sides of the jaws of the body, each center plate being also provided with guides to receive a bottom member of a body-jaw, and means, substantially as described, for drawing the members of the binding-section toward each other and retaining them in ad justed position, as described.

4. In a clamp, the combination, with asection comprising opposing spring-jaws curved outwardly and downwardly in opposite directions, and a sleeve attached to both of said jaws, of a binding-section comprising two members, each member consisting of a center plate having clamping-guides in its inner face at its lower end, and a series of transversely-arranged arms curved at their extremities, together with a tubular studprojecting inward from the said plate, and a connecting device adapted to extend from one stud to the other, for the purpose specified.
